“…Reportedly, the variation rate can be as high as 13% [1,9,21,30,31], which necessitates thorough examination of the vascular anatomy in the lower extremity prior to any intervention. Without a precise knowledge of anatomic variations in the branching pattern of the popliteal artery, it can be limb-threatening during a number of procedures in the lower limb, including arterial reconstructions in femoro-distal bypass graft procedures, embolectomy, and catheterization to treat lower limb ischemia in diabetic and ankle arthroscopy.…”

Aims: Knowledge about branching pattern of the popliteal artery is very important in any clinical settings involving the anterior and posterior tibial arteries. This study aims to elucidate the anatomical variation patterns and common types of anterior tibial artery (ATA) and posterior tibial arteries (PTA) in the general population in China. Material and methods: Anatomical variations of ATA, PTA, and peroneal artery were evaluated with ultrasound in a total of 942 lower extremity arteries in 471 patients. Results: Three patterns of course in the PTA were ultrasonographically identified: 1) PTA1: normal anatomy with posterior tibial artery entering tarsal tunnel to perfuse the foot (91.5%), 2) PTA2: tibial artery agenetic, and replaced by communicating branches of peroneal artery entering tarsal tunnel above the medial malleolus to perfuse the foot (5.9%), and 3) PTA3: hypoplastic or aplastic posterior tibial artery communicating above the medial malleolus with thick branches of peroneal artery to form a common trunk entering into the tarsal tunnel (2.4%). In cases where ATA was hypoplastic or aplastic, thick branches of the peroneal artery replaced the anterior tibial artery to give rise to dorsalis pedis artery, with a total incidence of 3.2 % in patients, and were observed more commonly in females than in males. Hypoplastic or aplastic termini of ATA and PTA, with perfusion of the foot solely by the peroneal artery, was identified in 1 case. In another case, both communicating branches of the peroneal artery and PTA entered the tarsal tunnel to form lateral and medial plantar arteries.Conclusions: Anatomical variation of ATA and PTA is relatively common in the normal population. Caution should be exercised with these variations when preparing a peroneal artery vascular pedicle flap grafting. Ultrasound evaluation provides accurate and reliable information on the variations.

Blood Oxygenation Level–Dependent Magnetic Resonance Imaging of the Skeletal Muscle in Patients With Peripheral Arterial Occlusive Disease

et al. 2006

Background-Blood oxygenation level-dependent (BOLD) magnetic resonance imaging (MRI) has been used to measure T2* changes in skeletal muscle tissue of healthy volunteers. The BOLD effect is assumed to primarily reflect changes in blood oxygenation at the tissue level. We compared the calf muscle BOLD response of patients with peripheral arterial occlusive disease (PAOD) to that of an age-matched non-PAOD group during postischemic reactive hyperemia. Methods and Results-PAOD patients (nϭ17) with symptoms of intermittent calf claudication and an age-matched non-PAOD group (nϭ11) underwent T2*-weighted single-shot multiecho planar imaging on a whole-body magnetic resonance scanner at 1.5 T. Muscle BOLD MRI of the calf was performed during reactive hyperemia provoked by a cuff-compression paradigm. T2* maps were generated with an automated fitting procedure. Maximal T2* change (⌬T2* max ) and time to peak to reach ⌬T2* max for gastrocnemius, soleus, tibial anterior, and peroneal muscle were evaluated. Compared with the non-PAOD group, patients revealed significantly lower ⌬T2* max -values, with a mean of 7.3Ϯ5.3% versus 13.1Ϯ5.6% (PϽ0.001), and significantly delayed time-to-peak values, with a mean of 109.3Ϯ79.3 versus 32.2Ϯ13.3 seconds (PϽ0.001). Conclusions-T2* time courses of the muscle BOLD MRI signal during postocclusive reactive hyperemia revealed statistically significant differences in the key parameters (⌬T2* max ; time to peak) in PAOD patients compared with age-matched non-PAOD controls.

“…Decision making before surgical or radiologic intervention in patients with arterioocclusive disease of the lower extremities depends on accurate delineation of the level, multiplicity, and severity of stenoses (3)(4)(5)(6). Numerous refinements in x-ray angiography, including replacement of translumbar arteriography with the transfemoral (or transbrachial) approach with a Seldinger technique, routine use of digital imaging and image subtraction, introduction of minipuncture angiography, and improvements in iodinated contrast material safety, have contributed to a procedure that has stood the test of time (3)(4)(5)(6). Nonetheless, the substantial morbidity and low but definite mortality rate are well recorded (7).…”
